Sigfox reckons is the only network technology in position to support battery-less devices for low-power wide-area (LPWA) IoT solutions, at least in early prototype mode today. Said Bertrand Ramé, senior vice president of international operations at Sigfox.
"It is not the first time Sigfox has showcased the technology. At its 2017 Sigfox Connect in Prague, in the Czech Republic, it showed that, just by opening an envelope, enough energy could be harnessed to trigger an embedded device to issue a message that the envelope was opened."
Ramé remarked: "All of a sudden, it opens up ideas and use cases that were not available or even thinkable before."
He added: "It is work in progress – the IoT sector is market in creation, after all, and the more innovation we can kick in to the process, the better it will be. This is what we are working on."
At its Sigfox Connect event in Berlin October, the firm unveiled a passive LPWA module, a transmitter, that takes power from an an electromagnetic wave as it comes into contact with Sigfox devices.
